Abstract

For a series of superconductors Bi2Sr2Can-1CunO2n+4+x (n=1~3), showing the critical temperatures Tc at about 20, 85 and 110K respectively, we have examined the mixing state of the phases, especially the microstructures at interfaces, by high-reso1ution transmission electron microscopy (HRTEM). 1-4) Here we show the results of observation on two kinds of specimens.
